Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Control module: TCS
TCS (Traction Control System) means that the control module always utilizes maximum friction on the driving wheels during acceleration. A limited amount of wheelspin is modulated by braking and requesting torque limitation from Trionic. The control module activates the pressure increase valve and pressure relief valve as well as the return pump to create and govern pressure to the driving wheels that are to be braked during wheelspin exceeding a specified limit.
